I just tried the suggested tip, but it didn't work. I have a Geforce4 Ti4200 64MB | Code: | cat /proc/driver/nvidia/cards/0
Model: GeForce4 Ti 4200
IRQ: 11
Video BIOS: 04.25.00.29.00
Card Type: AGP |
| Code: | cat version
NVRM version: NVIDIA Linux x86 NVdriver Kernel Module 1.0-3123 Tue Aug 27 15:56:48 PDT 2002
GCC version: gcc version 3.2.1 |
| Code: | cat host-bridge
Host Bridge: nVidia (unknown)
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x00000000 |
| Code: | cat card
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x00000000 |
but unfortunately agp is still disabled 
| Code: | cat status
Status: Disabled |
any ideas?
edit: also after i rebooted my /proc/driver/nvidia directory was gone! and there was a new directory in /proc/driver/ray_cs. so i ran startx and the nvidia directory and all the stuff inside it were recreated? what's up with that?
edit again: taskara just told me in a diff. thread that agp gart isn't supported yet for the nforce2 motherboard i have. oh well, i'll wait till nvidia releases them. | Quote: | I know you enabled it in the bios, but what I'm saying is that linux has no support for the nforce AGP gart.
Sure agp will work - I mean you can see your screen can't you?
but it won't have a specific driver loaded for it.
not until nvidia releases an agp driver, cause they keep all their stuff closed source. |

So the ray_cs deal was before you ran startx at all after a reboot? Not sure here, but possibly the nvidia stuff doesn't come into play until X is up and running. After all, agp gart doesn't do much when you're only in a console. |

I'm looking for if somebody have try to enable fast writes on a MB Abit KT7a (with via kt133) with Geforce2Pro and if there is no problem of stability ?
I can enabled it, but before trying I will prefer to know if it's a good idea or not 
If anybody answer me, I will try, but I prefer to know before  |

i would recommend removing xdm from the startup scripts when you try it, so you dont have to bot with the cd if it locks up your machine

|
|
On the latest driver release, this solution didn't work for fast write and SBA. I edited my /etc/modules.d/nvidia file to look like this and it worked.
| Code: | alias char-major-195 nvidia
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1 |
In the Nvidia 4191 driver release, they changed the module from "NVdriver" to "nvidia".
Good luck!

I gave this tip a try. Had no problems starting up fluxbox. We'll see if this is stable in a little while(in the past I could run for a while then it would lock up). Before(with Mandrake 9) I wasn't able to run with fast writes or agp greater than 2x, but I did things differently back then. Just for reference I'm using VIA KT266 MB with GeForce Ti 4200 128 MB(8x capable but my MB only supports 4x).
edit: It wasn't stable. Took a while but it eventually crashed, so I reverted to my previous settings. |

aw weak... I had to update my mobo's bios to support my new processor... and now /proc/driver/nvidia/agp/host-bridge says that Fast Writes are not supported... but it worked prior to my update...
hmmm... agp fast write or 200MHz more processor?
I think I will have to stick with no agp fast write... but it still really really sucks

| Just if you activated the fast write and it makes your X crash even you retired the fast write just compil again the nvidia module |

when i enabled sba and fw, my system
locks up when i run tvtime for a minute
or so.
before i ran tvtime, i ran glxgears, which
produced the same fps as without sba
and fw.
both things considered, i'll leave them off. |

fw and sba won't make a difference in glxgears
it'll only show in stuff that uses large textures, like games and stuff |

I have (apparently) had the same issue until I used both the latest kernel with the latest nvidia drivers. Also my glxgears performance was suffering.
However, I overcame those issues this evening, on the following system, with the included configuration details: | Code: | mobo: ABIT NF7-S rev 2 [the standard nforce2 ultra 400 chipset)
video card: GeForce FX 5600
sys-kernel/gentoo-dev-sources-2.6.3-r1 [AGPGART enabled]
media-video/nvidia-kernel-1.0.5336-r1
media-video/nvidia-glx-1.0.5336-r1 |
To emerge these (latest) keyword masked versions of the nvidia driver, add these two lines to /etc/portage/package.keywords: | Code: | media-video/nvidia-glx
media-video/nvidia-kernel |
Here is my /etc/X11/XF86Config's Device section: | Code: | Section "Device"
Identifier "NVAGP"
Driver "nvidia"
VendorName "nvidia"
Option "NvAGP" "3"
Option "CursorShadow" "yes"
Option "NoLogo" "yes"
Option "RenderAccel" "yes"
EndSection |
Here are my AGP results: | Code: | wblew@mortis wblew $ cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: AGPGART
AGP Rate: 8x
Fast Writes: Enabled
SBA: Enabled
wblew@mortis wblew $ cat /proc/driver/nvidia/agp/card
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
Registers: 0x1f000e1b:0x1f004312
wblew@mortis wblew $ cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: nVidia Corporation nForce2 AGP (different version?)
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
Registers: 0x1f00421b:0x00000312 |
Here are my glxgears results: | Code: | wblew@mortis wblew $ glxgears
7164 frames in 5.0 seconds = 1432.800 FPS
9204 frames in 5.0 seconds = 1840.800 FPS
9172 frames in 5.0 seconds = 1834.400 FPS
9177 frames in 5.0 seconds = 1835.400 FPS |
I hope this helps.

Same problem as rbonthond and christsong84
| Code: | $ cat /etc/X11/XF86Config | grep NvAGP
Option "NvAGP" "1"
|
| Code: | $ cat /etc/modules.d/nvidia
alias char-major-195 nvidia
alias /dev/nvidiactl char-major-195
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1
|
| Code: | $ cat /proc/driver/nvidia/agp/card
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
|
| Code: | $ cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: nVidia Corporation nForce2 AGP (different version?)
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
|
| Code: | $ cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: NVIDIA
AGP Rate: 8x
Fast Writes: Enabled
SBA: Disabled
|
My System:
| Quote: | mobo: Epox 8RDA+ rev 1.1
video card: GeForce 4 Ti 4200
sys-kernel/gentoo-dev-sources-2.6.3-r1 [AGPGART disabled, using NVIDIA driver]
media-video/nvidia-kernel-1.0.5336-r1
media-video/nvidia-glx-1.0.5336-r1 |
How can I get SBA enabled?
Thanks in advice. |

Crashes instantly with SBA and Fastwrites enabled. Crashes after about 8 days uptime randomly with Fastwrites enabled and SBA disabled. Rock solid stable with both off.
Specs:
Asus A7v Kt133
Crucial pc 133 Ram
MSI Geforce 4 ti-4200 64mb
Kernel 2.6.3-gentoo-r1
